Subject: [SIR-Mail] No.890: igs08_1780.atx: G064 launched, R714 reactivated From: Laura Sanchez Dear IGS colleagues! The absolute IGS antenna correction file (igs08_wwww.atx) has been updated. The new release is called ´igs08_1780.atx´. It contains the following changes: 1) The fifth Block IIF satellite launched on 21 February 2014 has been added: G30 (G064) The following PRELIMINARY phase center offset (PCO) values were assigned: PCO_X = 39.4 cm PCO_Y = 0.0 cm PCO_Z = 160.0 cm The COSPAR ID (2014-008A?) has not been confirmed yet. Source: > The US Air Force’s fifth GPS Block IIF navigation satellite was launched on Thursday night. Liftoff, from Cape Canaveral Air Force Station in Florida, via the United Launch Alliance (ULA) Delta IV rocket, came at the end of a nineteen-minute window, resulting in a T-0 of 8:59 pm Eastern (01:59 UTC on Friday). ... > GPS IIF-5, which is also numbered GPS IIF SV-5 and has Space Vehicle Number 64. It is expected to be given Pseudo-Random Noise (PRN) code 30. http://www.nasaspaceflight.com/2014/02/ula-delta-iv-launch-gps-iif-5/ 2) According to the Information-Analytical Centre, GLONASS-M satellite R714 was reactivated utilizing almanac slot 18.
